EVERETT E. THOMPSON, OF KAUFMAN, TEXAS.

STOVE-FLUE.

Specification of Letters Eiatent` Patented Feb. 5, 1907.

Application filed November 8,1905. Serial No, 286,370.

IO for to prevent the heat of the products of combustion passing through the Yllue from burning` or charring the woodwork between the ceilings and floors of buildings.

My invention will be particularly described hereinafter and illustrated in the accompanying drawings, in which- Figure 1.is a sectional view et a building, showing the application of my invention Fig. 2, an enlarged view of the flue and its appurtenances, the fire-casing being shown in section; Fig. 3, a detail of the screw-threaded sleeve for securing the parts of the Vflue together, and Fig. 4 a detail view ci one ct the hangers.

In the drawings similar reference characters indicate corresponding parts throughout the several views.

A represents a building in which my iinproved [lue is installed, B represents the loor-joists; O, the ceilings D, the floor; E, the rafters, and F a partition-wall.

1 represents the flue, which maybe made of any desired material-such as metal, terracotta, tehaving a series of notches 2 therein for the purpose to be hereinaf ter described.

3 represents the pipes connected with stoves 4 and connected with the lower end of flue 1 by means of a T-joint 5, which is secured to said flue 1 by means of an interiorlythreaded coupling 6. The exterior of coupling 6 is also screw-threaded, as shown at 7, to receive a nut 8 to support the plate 9, which is provided with a hole 9d to receive the tlue 1.

In installing my flue in position a large hole is cut in the floor and ceiling slightly smaller than the size et' plate 9, which when in position completely covers said hole. On the upper side of plate 9 is secured a fireproof casing consisting of a hollow annular box 10, having its outer wall 11 cylindrical, while its inner wall 12 is conical in cross-section, as shown in Fig. 3.

The plate 9, inclosed by the box 10, is provided with a number of holes 13, while the upper side of the box 1() is also provided with holes 14, said holes 13 and 14 being provided to secure ventilation through the box to prevent it becoming heated sufficiently to burn. the woodwork between the floors and under the roof.

15 represents a collar-brace made of strapiron, having its middle portion curved, as shown at 16, to hall surround 'the smoke-flue 1 and its ends provided with a series ci holes f 17 to receive the nails or screws to secure the brace to the tops of the adjacent joists B.

1S represents a hall-circular strap to mate with the half-curved portieri 16 and having ears 19 extending 'l'roin its ends, with holes 19L therein to receive screw-bolts 20, run through holes 15 in brace 15 to draw the two parts 15 and 19 together to clasp the llue 1.

2l. represents a set-screw secured in a hole 21L in curved portion 1G, which seats in one of the notches 2 and serves to support the llue.

22 represents a top plate to cover the opening in the iloor made for the passage o1' ilue 1, and itis provided with a central hole 22, through which the llue extends.

The construction of plates 9 and 22 and Vlireproof casing, consisting of the annular hollow box 10, is repeated in passing through each ceiling and ileor and is also used in passing the smoke-pipes B through each partitionwall F, as shown in the drawings.

23 represents a collar-brace similar in construction to the brace 15, having its extended ends 24 bent so as to t the top or bottom edges ot the roof-rafters E and with a mating portion 25, secured by means ot' bolts 26 to the part 23 27 represents a set-screw to secure the brace to the ilue 1 in one of the notches 2.

2S represents a sleeve mounted on the part of the llue 1 extended outside of the roof of the building and .having a conical-shaped lower portion 29 to shed water and prevent it from following the Vflue down into the huilding A, the lower edge et the lower portion 29 being soldered or otherwise secured to the tin or other covering of the roof. The upper edge ol the sleeve 28 is also made water-tight in its relation te the flue by means ci solder or other agent. The top of the ilue is provided with a chimney-cowl of any desired construction, the T construction indicated by the character 30 being used for illustration only.

My improved ilue is designed to be used to the exclusion 0il the ordinary construction 0l brick `flue and is superior thereto in that the IOO IIC

brick flue is subject to cracking and disintegration and is ditlicult to keep clean because of its permanent nature, While my flue is adapted to dismemberment and removal for cleaning and does not disintegrate in use.

Having thus described my invention, what I claim is 1. A smoke-ihre comprising a pipe having notches therein, said ilue being adapted to extend through openings in the iioors of buildings, collar-braces having extended ends secured to the rafters and joists of the building, said collar-braces surrounding said flue, and set-screws secured in said collar-braces and adapted to seat in one of the notches in the flue, substantially as shown and described.

2. A smoke-'liuc comprising a pipe having notches therein, said iiue bei-ng adapted to extend through openings in the iioors of buildings, collar-braces made of strap-iron having their middle portion bent to partly surround the flue, and having extended ends secured to the rafters and joists olf' the buildings, and mating members to iit around the balance of the flue, and secured to the i` rs -named member of the collar-brace by means of' bolts, and set-screws secured in the collar-braces and adapted to seat in the notches in the flue, substantially as shown and described.

3. A sniole-i'lue for buildings comprising a pipe extended through enlarged holes in the ceilings and the floors of the building, plates to cover said holes in the iloors and ceilings, the plate covering the hole in the ceiling having secured to its upper side a hollow annular box, the inner surface of said box being conical-shaped, the plate and upper surface of said box provided with air-holes, and means to secure the plate in position, substantially as shown and described.

4. A smoke-flue for buildings comprising a pipe extended through enlarged holes in the ceilings and floors of the building, plates to cover said hoies in the floors and ceilings, the plate covering the hole in the ceiling having secured to its upper side a hollow annular box, the inner surface of said box' being conical-shaped, the plate and upper surface of said box provided With air-holes, collar-braces for securing the Hue in position consisting of two mating members shaped to surround the flue and secured together by screw-bolts, and set-screws to secure said braces to said ilue, substantially as shown and described.

In Witness whereof I have hereunto set my hand in presence of tWo subscribing Witnesses.

EVERETT E. THOMPSON.
